Description

Technical Field

[0001] The utility model relates to the technical field of booster pumps, in particular to a shock-absorbing water outlet cavity of a booster pump. Background Art

[0002] As a common water pump, the working principle of booster pump is mainly to rely on the reciprocating motion of the diaphragm to achieve the suction and discharge of liquid. However, there are some problems that cannot be ignored when the traditional booster pump is working, especially in the design of the water outlet cavity structure.

[0003] Conventional booster pumps usually connect the water outlet chamber directly to the outlet. Although this design simplifies the structure, it will cause a sharp increase in water flow velocity when the water flow rate is large. This rapid change in water flow will not only cause resonance inside the pump body, but also cause obvious vibration and noise. These vibrations and noise not only affect the operating stability of the equipment, but may also have a negative impact on the surrounding environment and the health of operators. In addition, long-term vibration may cause increased wear of the pump body, shorten the service life of the equipment, and increase maintenance and replacement costs.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0010] In order to further solve the technical problem to be solved by the utility model, in a booster pump shock-absorbing water outlet cavity provided by the utility model, the width m of the water gap is 0.1mm-1mm.

[0011] In order to further solve the technical problem to be solved by the utility model, the utility model provides a booster pump shock-absorbing water outlet cavity, in which the side wall of the secondary cavity is provided with a channel opening connected to the water outlet pipe, and each water gap is staggered with the channel opening in the circumferential direction.

[0016] In the utility model, the separation cover separates the water outlet cavity into two cavities, and a plurality of water gaps are provided on the side wall of the separation cover. The design of these gaps forms a water communication channel between the main cavity and the secondary cavity. The water gap is directly opposite or obliquely opposite to the side wall of the main cavity, which can change the flow direction of water, avoid directly rushing into the water outlet pipe, and can also slow down the flow rate of water through the narrow water gap. When the fluid flows into the secondary cavity, it can undergo a certain diffusion and rotation before entering the water outlet pipe, forming a relatively stable flow state. Therefore, the water gap can ensure the smoothness of water flow, reduce the impact caused by the change in flow rate, and improve the overall stability of the pump body.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figures 1 to 4 Shown is a booster pump shock-absorbing water outlet cavity, the structure of which is designed to effectively reduce the vibration and noise generated by the booster pump during operation and improve overall work efficiency and stability.

[0024] The system of the booster pump mainly includes an inlet pipe 1, an inlet chamber 2, an outlet chamber 3 and an outlet pipe 4. The inlet pipe 1 is responsible for introducing the liquid into the pump body, while the inlet chamber 2 serves as a storage and regulation area for the liquid. A first one-way valve 5 is arranged between the inlet pipe 1 and the inlet chamber 2, and its main function is to ensure that the liquid can only flow in one direction and prevent the occurrence of backflow, thereby ensuring the normal operation of the pump body. In the inlet chamber 2, a water pump drive device 6 (usually including a motor, an eccentric swing rod, etc., which is a prior art and will not be repeated here) is provided. The device is the core component of the booster pump and is responsible for driving the diaphragm to reciprocate to achieve the suction and discharge of the liquid. At the same time, a second one-way valve 7 is arranged between the inlet chamber 2 and the outlet chamber 3 to ensure that the liquid can only flow from the inlet chamber 2 to the outlet chamber 3, further enhancing the working efficiency of the pump.

[0025] The design of the water outlet chamber 3 is particularly critical, and it consists of a main chamber 31 and a secondary chamber 32. The second one-way valve 7 is located at the bottom of the main chamber 31, and a separation cover 33 protruding toward the secondary chamber 32 is provided between the main chamber 31 and the secondary chamber 32. The separation cover 33 not only separates the water outlet chamber 3 into two chambers, but also improves the flow characteristics of the liquid.

[0026] Specifically, a plurality of water gaps 331 are provided on the side wall of the partition cover 33, and the design of these gaps forms a water communication channel between the main cavity 31 and the secondary cavity 32. The water gaps 331 are directly opposite or obliquely opposite to the side wall of the main cavity 31, which can change the flow direction of water, avoid directly rushing into the water outlet pipe 4, and can also slow down the flow rate of water through the narrow water gaps 331. When the fluid flows into the secondary cavity 32, it can undergo a certain diffusion and rotation before entering the water outlet pipe 4, forming a relatively stable flow state. Therefore, the water gaps 331 can ensure the smoothness of the water flow, reduce the impact caused by the change in flow rate, and improve the overall stability of the pump body.

[0027] Finally, the secondary cavity 32 is connected to the water outlet pipe 4 , and the liquid is smoothly discharged through the water outlet pipe 4 after passing through the secondary cavity 32 .

[0028] This structural design not only effectively reduces the vibration and noise that may be generated when water is discharged, but also improves the working efficiency and service life of the pump.

[0029] More specifically, a plurality of guide plates 332 are provided on the outer side of the separation cover 33, and the design of these guide plates 332 is intended to further optimize the flow characteristics of the fluid in the water outlet chamber 3. The arrangement of the guide plates 332 can not only effectively guide the flow of the fluid, but also reduce the turbulence and fluctuation that may be generated when the fluid passes through the water gap 331, thereby reducing vibration and noise.

[0030] Drain plates 332 are provided on both sides of each water gap 331, forming an orderly flow channel. This design allows the fluid to enter the secondary cavity 32 more smoothly when passing through the water gap 331, thereby effectively alleviating the impact force of the fluid. In actual operation, when the fluid passes through the water gap 331, it is guided by the drain plates 332, the flow path is optimized, and the sudden change of flow rate and pressure fluctuation are reduced.

[0031] In addition, the guide plates 332 on both sides of the water gap 331 are arranged in an eight-shaped pattern. This layout design not only increases the effective area of ​​the guide plates, but also promotes the laminar flow state of the fluid, further reducing the energy loss in the flow. The guide plates 332 arranged in an eight-shaped pattern can effectively guide the fluid to flow along a predetermined path, so that when the fluid enters the secondary cavity 32, it presents a relatively uniform flow rate and pressure distribution, thereby improving the stability and efficiency of the water outlet.

[0032] More specifically, the width m of the water gap 331 is 0.1 mm to 1 mm. Such a width selection is based on the basic principles of fluid dynamics and can effectively balance the flow velocity, pressure loss and flow stability of the fluid when passing through the gap.

[0033] More specifically, the side wall of the secondary cavity 32 is provided with a channel opening 34 connected to the water outlet pipe 4. The channel opening 34 is located on the side wall of the secondary cavity 32 to ensure that the fluid does not directly enter the water outlet pipe 4 with high impact force when discharged. This design can effectively reduce the straight-forward phenomenon of water flow, thereby slowing down the flow rate and reducing noise during operation. By setting the channel opening 34 on the side wall, when the fluid flows out of the secondary cavity 32, it can undergo a certain degree of diffusion and rotation before entering the water outlet pipe 4, forming a relatively stable flow state. This flow characteristic not only helps to reduce the impact force of the fluid, but also significantly reduces the noise problem caused by excessive flow rate.

[0034] In addition, the staggered design of each water gap 331 in the circumferential direction is also to further prevent the water flow from directly rushing into the outlet pipe 4 from the water gap 331. Through this staggered layout, it can be ensured that the fluid will undergo a certain path adjustment and flow transformation after leaving the water gap 331, forming a more uniform and stable flow state. This design allows the fluid to obtain an appropriate "deceleration" process before entering the channel opening 34, thereby avoiding fluid vortex and noise increase caused by sudden flow velocity changes.

[0035] More specifically, a number of partitions 333 are designed between the outer side of the partition cover 33 and the inner wall of the secondary cavity 32. The main function of these partitions 333 is to effectively isolate the water gap 331 from the channel opening 34 to ensure that the fluid can form a more ideal flow state during the discharge process. When the fluid flows out of the water gap 331, it must flow over these partitions 333 before entering the channel opening 34. Such a design can play multiple roles: on the one hand, the presence of the partitions 333 can reduce the flow speed of the fluid and prevent the fluid from directly impacting the channel opening 34, thereby reducing the noise and vibration caused by the impact force; on the other hand, the partitions 333 can also cause the fluid to undergo a certain turbulent transition during the flow process, which helps to evenly distribute the fluid and improve the overall drainage efficiency.

[0036] More specifically, the top surface of the separation cover 33 is lower than the top surface of the secondary cavity 32 .

[0037] More specifically, an opening is provided at the top of the secondary cavity 32 , and a top cover 321 is provided at the opening.
